I would like to use Z-wave for doorcontacts and maybe also movement sensors. And have been looking at the different z-wave products. Maybe I have overlooked something, but I did not find any switches that can be placed behind the old on/off switch so that the old switch and LinuxMCE can switch the lights. Reason for keeping the old on/off switches are that the Merten & co don't look like those I have got and I would really not like to change all switches in my house

Have you got any suggestions ? Or do I have to use PLCBUS or other things ?

And another question - what happens when the battery of a Z-wave product is empty ? Is the device shown as missing or does LinuxMCE tell me to replace batteries (that would be nice ) ?

Background info.I am building a LinuxMCE system in my new house and at the moment I am looking into the things I need.I live in Denmark (Europe)

But can this 506004 be used for more than one device ? Meaning can I connect 4 different devices and it will be able to send four different trigger signals (turn on four different lights) ... ? Or does all four connections trigger the same signal/light ?

If it can control four things it would be a really nice thing One could use it for a lot of things. Like using normal PIR's and then connect four PIRS to it. Or smoke alarms or a Doorbell and windows contacts and so on ... Any idea how long the batery will last in this one ?

Back to the battery low question. Really nice that you have something in planning But what about now ? If the device runs out of battery it will probably dissapear and will that be noticed ?

So this can sort of be a cheaper replacement for the GC-100 in cases where one would like to have some switches for doors/windows, PIR's and so on. Really Great Only bad thing is that one has to change the batteries once and a while.

now I had some more time looking into the original problem - keep my old switches togehter with z-wave. Unfortunately I am not that happy with what I have found. What I am looking for is something like the AW12 for X10. Click here

A module that does not need a battery to work so that the switches will always work manually. I would just connect the old manual switch to the module and it then takes over switching the lights.

If I go for a merten 507001 in the lamp in the ceiling and a merten 506004 in the switch - it would stop working if the 506004 ran out of battery

Eljo has these devices that you put behind the existing switches. However I have found out that they are really big and it gets tight. In a normal "hole" I don't recommend actually to put these behind since it also gets quite warm. So I am abit undecided whether these are good or not if you still want local control without battery(my concern as well). Seem like they count on that you buy the battery switch together with these..and then I would go for Merten..

Btw.. I have asked my friend about the prices, not a very big difference compared to zwave4u but if possible to collect locally you probarbly save the freight at least. Will get back to you on that..

hehe, yes, i think you could abuse their load switches as remote switch as they support group associations :-)And yes, you can mix EnOcean and Z-Wave with LinuxMCE. But be aware that the "bridging" only works when the core is up..

Well maybe a bit lazy I would have overread what it says there and not found it. It could be a solution, but it is not 100% what I wanted.

I am looking for a module that can be put in the box behind the old on/off switch. 1. We then connect the old on/off switch to the module2. The module is then connected to the wires that were previously on the on/off switch. 3. With the old on/off button we can tell it (the module) to switch the light on/off. 4. With z-wave we can also switch the light on/off

very Nice Could it also alternatly be handled by mail ? I assume the rest of the family would not care about knowing that the battery is empty Or can they be sent to the First user that was setup on the core ?
